Abstract

A cable apparatus having an increased linear pullout resistance and related methods is disclosed. The apparatus includes a metal tube. At least one conductor is positioned within the metal tube. An armor shell is positioned exterior of the metal tube and the at least one conductor. A polymer material is abutting the metal tube, wherein the polymer material includes therein at least one additive, wherein the polymer material with the at least one additive remains substantially inert during a recrystallization process.

Claims

1. A cable apparatus comprising:

a metal tube;

at least one conductor positioned within the metal tube;

an armor shell positioned exterior of the metal tube and the at least one conductor; and

a polymer material abutting the metal tube, wherein the polymer material includes therein at least one additive, wherein the polymer material with the at least one additive remains substantially inert during a recrystallization process.

2. The cable apparatus of claim 1, wherein the polymer material is positioned between the metal tube and the at least one conductor.

3. The cable apparatus of claim 1, wherein the polymer material is positioned between the metal tube and the armor shell.

4. The cable apparatus of claim 1, wherein the polymer material is positioned between the metal tube and the at least one conductor and between the metal tube and the armor shell.

5. The cable apparatus of claim 1, wherein the at least one additive within the polymer material further comprises 10% to 30% of the polymer material.

6. The cable apparatus of claim 1, wherein the at least one additive within the polymer material further comprises 4% to 80% of the polymer material.

7. The cable apparatus of claim 1, wherein the at least one additive further comprises at least one of talc, glass beads, nano clay, barium sulphate, calcium carbonate, and silicate.

8. The cable apparatus of claim 1, wherein the at least one additive is a non-expandable additive.

9. The cable apparatus of claim 1, wherein polymer material with the at least one additive has an operational dimension, the operational dimension measured from an exterior surface of the polymer material with the at least one additive to an interior surface of the polymer material with the at least one additive, wherein the operational dimension is constant during operational use of the cable apparatus.

10. The cable apparatus of claim 1, wherein a pullout resistance factor of the polymer material with at least one additive remains substantially unchanged when the polymer material with at least one additive is subjected to an operational catalyst.

11. The cable apparatus of claim 10, wherein the operational catalyst further comprises at least one of:

a temperature increase; and

a pressure increase.

12. A method of manufacturing a cable apparatus having an increased linear pullout resistance, the method comprising the steps of:

positioning at least one conductor within a metal tube;

affixing an armor shell exterior of the metal tube and the at least one conductor; and

applying a polymer material having at least one additive therein interior of the armor shell and in abutment to the metal tube, wherein the polymer material having the at least one additive remains substantially inert during a recrystallization process.

13. The method of claim 12, further comprising the step of mixing the at least one additive with the polymer material, wherein the at least one additive includes at least one of:

talc, glass beads, nano clay, barium sulphate, calcium carbonate, and silicate.

14. The method of claim 12, wherein the at least one additive within the polymer material further comprises 4% to 80% of the polymer material.

15. The method of claim 12, further comprising the steps of:

identifying a first pullout resistance factor of the polymer material having the at least one additive during a non-operational state of the cable apparatus;

subjecting the polymer material having the at least one additive to an operational catalyst, wherein the operational catalyst includes at least one of;

a temperature increase; and

a pressure increase; and

identifying a second pullout resistance factor of the polymer material having the at least one additive when it is subjected to the operational catalyst, wherein the second pullout resistance factor is substantially equivalent to the first pullout resistance factor.
